    摘要: A tunable acoustic resonator device has a piezoelectric medium as a first thin film layer and a tunable crystal medium as a second thin film layer. The tunable crystal medium has a first acoustic behavior over an operating temperature range under a condition of relatively low applied stress and a second acoustic behavior under a condition of relatively high applied stress. The acoustic behaviors are substantially different and, consequently, the different levels of applied stress are used to tune the acoustic resonator device. Compared with the tunable resonator device consisting of only tunable crystal medium, a device having both the piezoelectric and tunable crystal medium has advantages such as larger inherent bandwidth and less nonlinearity with AC signals. The device also requires a smaller applied stress (i.e. bias voltage) to achieve the required frequency tuning.

    摘要: A superlattice crystal resonator having a substrate of a dielectric acoustic superlattice material, both sides of which substrate are plated with electrodes. The resonator can be a one-port resonator if the electrode on both sides is a single electrode, or it can be a two-port resonator if the electrode on one side is a single electrode and the electrode on the other side is a bipolar electrode. The superlattice crystal resonator can be used as a superlattice crystal filter, either in the form of a monolithic superlattice crystal filter formed by a two-port superlattice crystal filter, or in the form of a combined superlattice crystal filter where a number of one-port superlattice crystal resonators are interconnected in various circuitry configurations with or without other electronic components, such as capacitors, inductors, and resisters.

    摘要: A tunable filter circuit having inputs IN1-IN2 and outputs OUT1-OUT2, comprising at least a primary four-pole circuit including in cascade: a first varactor having a first electrode connected to IN1 and a second electrode; a first inductive resistor connected between the second electrode of the varactor and input IN2, a secondary four-pole circuit comprising four BAW resonators. First and second of these resonators have a first electrode connected to a first input of the secondary four-pole circuit and a second electrode connected to first and second outputs of the secondary four-pole circuit, respectively. Similarly, third and fourth of these resonators have a first electrode connected to a second input of the secondary four-pole circuit and a second electrode connected to the second and first outputs of the secondary four-pole circuit, respectively. The circuit further comprises a second inductive resistor connected in parallel to the first and second outputs of the secondary four-pole circuit and a second varactor having a first electrode connected to the first output of the secondary four-pole circuit and a second electrode for connecting a second primary four-pole circuit having the same structure. This allows realization of a particularly effective tunable filter circuit with only four inductive resistors.
